Acute and chronic toxicity assessments of 17β-estradiol (E2) and 17α-ethinylestradiol (EE2) on the calanoid copepod Acartia clausi: Effects on survival, development, sex-ratio and... by Emna, Djebbi

“…Embryos showed non-monotonic dose-response and hatching success was significantly reduced at low realistic concentrations of E2 (0.005, 0.5, and 5 μg L-1) and EE2 (0.05 and 5 μg L-1).Survival, development and sex ratio of A. clausi to EE2 exposure at 1 and 100 μg L-1 were also determined during a life cycle experiment. …”

Association between Insulin and Nitric Oxide in Human Retinal Microvascular Endothelial Cells in vitro by Rizk, Nasser Moustafa

“…In conclusion, this study demonstrated that Hyperglycemia causes an increase in ROS/oxidative stress and apoptosis, while insulin promotes a significant decrease in ROS and apoptosis, eNOS mediated NO production increases with hyperglycemia but remarkably decreases with insulin treatment after 1 hour, 2 hours and 4 hours, insulin could counteract the hyperglycemic effect on AKT/pI3 kinase which mediates NO production and VEGF-A, decreased adhesion molecules p-selectin involved in barrier disorder of retinal endothelial cells. …”

Alveolar bone changes following bi-maxillary vertical molars' movements using clear aligners by Al-Warafi, Leena Ali

“…Result The patients were divided into two groups: extrusion (48.9%, n = 65 molars’ root) and intrusion (51.1%, n = 68 molars’ root) group. There was a significant decrease in the alveolar bone changes in the buccal surface of the mandibular right and left 1st molars in the extrusion group (-1.05 ± 0.97, -0.76 ± 1.12 mm, respectively) and the maxillary left 2nd molars in intrusion group (-0.42 ± 0.77 mm), and the lingual surface of intrusion of the mandibular left 1st molar (-0.64 ± 0.76 mm). …”

Numerical simulation of stall development into surge and stall control using air injection in centrifugal compressors by Halawa, Taher

“…Results also showed that during surge, forces on the impeller blades increase to nearly double of its initial value and then decrease again. By using air injection at the vaneless region with different injection angles, it was found that injection with angle of 30° has a good effect on preventing surge and minimizing the pressure fluctuations comparing to other injection angles results. …”
